Why doesn't everyone use nuclear fission power?

Fusion reactor

As early as the 1980s, fusion power was cited as a potential opportunity to partially solve the energy problem. The role of fusion in the public debate has changed little since then. Fusion is still seen as an abstract hope about which the population is poorly informed. Critics therefore speak ironically of the "fusion constant". What is meant is the constant period of time that fusion energy will supposedly still need in order to be able to become part of an electricity mix.

The European Union has its own sub-organization to coordinate research into fusion power, the EFDA (European Fusion Development Agreement). The European Atomic Energy Community EURATOM is the sponsor and initiator of major projects.

In addition to EURATOM, Japan, Russia, South Korea, the United States and the People's Republic of China are equal partners in the construction and operation of ITER. France's then President Jacques Chirac said at the start of the ITER research reactor in 1999 that it was "the largest research project since the international space station". The ITER is being built as an international project in Cadarache in the south of France. For many critics, the acceptance and image problems of the nuclear fission force are also carried over to the technology of fusion energy. Both are therefore indiscriminately called “nuclear power” by critics and thus viewed negatively. Fusion power has found its way into popular culture, especially in space travel literature, science fiction or simulation games. In the classic game "Civilization", "Fusion Energy" is one of the most advanced known technologies that a player can research.

Fusion reactors thought of as networked

Fusion energy is also called "the infinite energy", "the energy of the universe" or the "true solar energy". In fact, the sun gets its energy from permanent fusion processes inside. The conditions of the sun, especially the extremely high pressure, cannot be achieved on earth. Therefore, fusion reactors literally have to get hotter than the sun - the plasma inside the reactor is heated to 100 million degrees Celsius, for example by microwaves. The sun has a temperature of 15 million degrees Celsius inside, and about 5500 degrees Celsius on the surface.
